Project Summary

In 2000, the U.S. Geological Survey (USGS), in cooperation with the University of New Orleans (UNO) and the U.S. Army Corps of Engineers (USACE), conducted geologic surveys in Barataria Bight from Sandy Point to Belle Pass, LA (Study Area Map). Sediment cores were collected as part of the USGS Subsidence and Coastal Change (SCC) Project, which included the Barataria Sand-Resource Study (bss) vibracore surveys (Kindinger and others, 2001). This report also contains information from other cruise data sets, including the Cheniere Ronquille, LA, data (CR83) and the Plaquemines, LA, data (P86). The sediment data for these cruises were obtained by the Louisiana Geological Survey (LGS), the Louisiana Department of Natural Resources (LDNR), and Alpine Ocean Seismic Survey, Inc., as part of the near shore sand resource inventory of "Louisiana Sand Resource Inventory 1985 Vibracore Services" (Suter and others, 1991; Alpine Ocean Seismic Survey, Inc., 1986). Additionally, this report also includes the U.S. Army Corps of Engineers EUSTIS borehole cores (B-#). EUSTIS is the type of drill rig used to obtain the borehole cores and is used as name identifier for the USACE borehole cores presented herein. These cores are presented on a separate map with links to the description profiles and grain-size data that can be found by clicking on the USACE EUSTIS link.

This report serves as an archive of vibracore data collected during field activities of Subsidence and Coastal Change (SCC) 00SCC01, 00SCC03, 00SCC05 (collectively noted in the report as 00SCC) by the U.S. Geological Survey, CR83 (Cheniere Ronquille, LA) and P86 (Plaquemines, LA) by the Louisiana Geological Survey and the Louisiana Department of Natural Resources and borehole data collected in 2000 for the U.S. Army Core of Engineers (USACE-EUSTIS). Data presented here include the sections Vibracore Description Sheets, Interpreted Core Classification Profiles, Grain-Size and Penetrometer Data, core location Maps and Core Data Table of all core data analysis files, and vibracore Photographs. Additional data include Field Activity Collection System (FACS) logs and scanned observer's logbooks (Field Logs), as well as formal Federal Geographical Data Committee (FGDC) Metadata. Please refer to the Acronyms page for explanation of all acronyms and abbreviations used in this report. The data are in XLS, PDF, GIF, JPEG, and RTF formats and may be downloaded and processed with commercial or public domain software such as Microsoft Office or Text Editor (Software). PDF files may be viewed using Adobe Reader.

Sediment core collection

Sediment samples for cruises 00SCC, CR83, and P86 were collected using a vibracore system. This system is capable of collecting sediment cores in unconsolidated sediments with penetration to 20 feet (ft) in depth. The USACE EUSTIS borehole cores used a different method, one that uses a boring technique to penetrate deeper sand deposits. Detailed information on the vibracore, borehole core collection, and sediment core description processes and on measurement, sampling, and data analysis is found in the Methods section.

Note: All sediment core data are in the Core Data Table linked to the cores on the Study Area Map for all vibracores (00SCC, CR83, and P86) and the cores on the USACE EUSTIS map for all borehole cores. Clicking on a core or core ID on the Study Area Map pages will bring forth a table that contains all sediment core data and displays the specific core information. The back button returns the user to the Study Area Map section. The sediment table (includes data from all cruises: USACE EUSTIS borehole cores (B-#), 00SCC (bss cores), CR83, and P86) contains core ID and five other columns containing previews and downloadable files for vibracore description sheets, interpreted core classification profiles, grain-size data, penetrometer data, and photographs.

Some vibracores have differences in naming schemes; please see the Metadata for clarification on cruise ID and core ID naming schemes and identification codes. Detailed information about the each cruise can be found in the digital FACS field and equipment logs. Please refer to the Methods page for detailed descriptions on each type of sediment data analysis. Also, information on the digitizing process for interpreted core classification profiles can be found in Flocks this volume (see Software page). Step-by-step instructions on the process can be obtained from the FISC. Contact James Flocks (jflocks@usgs.gov) for more information.
